Maybe we can have an example for disaggregated serving.

[liurupeng]

@kerthcet right now we don't have something public for the example, probably with release v0.5.0

[ahg-g]

@liurupeng can we plan for the next release and decide on a date please?

[ahg-g]

A couple more:

• Change default of restart policy to RecreateGroupOnPodRestart #204
• Add group size as an env var by default #203

[liurupeng]

sg! thanks @ahg-g

[liurupeng]

Target release date will be Sep 13

[kerthcet]

Should we release today, I'm waiting for the feature #190, I can pick the left one.

[liurupeng]

@kerthcet sure, feel free to pick up this one

[kerthcet]

Created #214

[ahg-g]

@kerthcet do you want to create the release?

[liurupeng]

Sorry for the delay, just created the release. Please approve the release, thanks! @ahg-g @kerthcet

[kerthcet]

Maybe we can start with milestone next release? But seems we still need a release issue for discussion?

[liurupeng]

@kerthcet do you want to drive the next release?
